Only one issue I faced:
On the day of my check-in, there was a very unpleasant smell coming from the bathroom and the smell was very apparent in the whole apartment. I texted the host about it but it seems like he ignored my text because he was responding when we were talking about other things. The host only replied regarding this issue on the last day (5 days later) when he wanted to make arrangements regarding the check-out.
I had to do my own cleaning up and washed the toilet. However, it seems like the smell was probably due to the ventilator or one of the pipes as the smell returned the following day. The host could have replied me on that day itself or even the following day to handle this issue. This is definitely one area for improvement.
Other that this issue which I faced, pleasant place and location.
